I have unpredictible behavior when spiders or roaches are crawling on me, it’s an automatic reaction I can’t seem to control. Im not really afraid of spiders or roaches so no phobia involved. Once I almost broke my arm, I hit it really hard to a wall to get the thing off.

Is there any hope for me to tame these reactions?

If you're serious about it, the way that I (accidentally) found that works is to keep some spiders and roaches as pets. I used to be the same way, involuntarily flinching whenever a large enough insect would crawl on me until I adjusted to being around them all the time. The roaches and smaller spiders don't trigger any kind of involuntary reflex anymore. I do still flinch when the largest spiders (> 5 inch leg span) move very quickly while I'm doing maintenance but I'm pretty okay with that, especially because one of them could put me in the hospital.

> it's easy to imagine the poorer consequences had I been a little further in my journey.

The wasp would have been fine.

Makes you wonder how many cause unknown single vehicle crashes where the driver dies are the result of insects.

Some people may view this scene[0] as overly dramatic, whereas I think it's perfectly understandable once it happens to you.
